Hello, yesterday we bought 6 quail from Jefferson feed. They are not sexed (cotournix quail excuse my spelling lol.) I'm wondering if there is anyway to tell the sex. Also how are they in southern climates like new orleans in the winter. They will be outside in a custom coop. Is it possible for them to live with ducks? Any advice keeping them healthy and laying would be helpful. Also once i figure out the sex. How many females to male ratio is good?
